HMT HSS SilverMax Weldon Twist Drill 8.5mm (M10 Tap Size)

SilverMax Weldon Shank HSS Twist Drill Bit

The SilverMax Weldon Shank HSS Twist Drill Bit is designed for fast, accurate drilling of smaller diameter holes using a magnetic drill. Ideal for pilot holes and tapped-hole preparation up to M12, these drills provide a convenient alternative to using a pistol drill or fitting a chuck into a mag drill.

With a standard Weldon shank, the drill bit fits directly into compatible magnetic drills, helping reduce setup time and improve drilling stability. This is especially useful where a drill chuck may not provide enough stroke or where repeated small-hole drilling is required.

Made from high-quality, fully ground HSS steel, these twist drill bits are built for long service life and reliable performance across a range of materials. They help reduce operator fatigue, improve control and make drilling smaller holes in steel safer and more efficient.
